Wiring Mode Of Circuit Breaker
1, the board after wiring mode: The biggest feature of the rear wiring of the board is that you can replace or repair the circuit breaker, do not have to reconnect, only the front level power supply should be disconnected.
Because of the special structure, the product has been configured according to the design requirements of the special mounting plate and mounting screws and wiring screws, it is necessary to pay special attention to the high capacity circuit breaker contact reliability will directly affect the normal use of circuit breakers, so the installation must be paid attention to, in strict accordance with the requirements of the manufacturer for installation.
2. Plug-in wiring: on the mounting plate of the complete set of devices, install the mounting seat of a circuit breaker, install 6 plugs on the seat, and have 6 sockets on the connecting plate of the circuit breaker. The mounting seat has a connecting plate on the face or a bolt after the mounting seat, and the mounting seat is pre-connected to the power cord and the load line. When used, insert the circuit breaker directly into the mounting seat. If the circuit breaker is broken, just pull out the bad and replace it with a good one. Its replacement time is shorter than the front of the board, the rear wiring of the board to be short, and convenient. Because Plug and pull need a certain amount of manpower. Therefore, China's plug-in products, its shell frame current limit to a maximum of 400A. This saves maintenance and replacement time.
Plug-in circuit breaker should be installed to check whether the circuit breaker plug is pressed, and the circuit breaker should be securely fastened to reduce contact resistance, improve reliability.
3, Drawer type wiring: circuit breaker in and out of the drawer is rotated clockwise or counterclockwise by the rocker, in the main circuit and two of the circuit are used Plug-in structure, omitting the necessary isolator of the fixed type, to achieve a second use of the machine, improve the economy of use, at the same time to the operation and maintenance has brought great convenience, increased security, reliability. In particular, the main circuit of the drawer seat touch seat, can be with NT type Melt circuit breaker touch seat general.
